"The Bonfire of the Vanities" By Tom Wolfe
Here's what Wikipedia has to say:
The Bonfire of the Vanities is a 1987 novel by Tom Wolfe. The story is a drama about ambition, racism, class politics, and greed in 1980s New York City, and centers on three main characters: the successful, arrogant, and very self-conscious bond trader Sherman McCoy, Jewish Assistant District Attorney Larry Kramer, and British expatriate journalist Peter Fallow.

Although the premise seems rather serious, it is also has a lot of humor in it. Wolfe really get's into the heads of the main characters. And, as you'll quickly find out, Sherman McCoy is a classic. He refers to himself as the Master of the Universe, complete with a "Yale Chin".
It's a classic 20th century novel, I think you'll enjoy it. It is a tad long, 600-700 pages in paper-back.
